Embodiment 1

[0033] Smash 10kg of fresh purslane (or chop 1kg of dried purslane) into 60kg of aqueous solution and soak for 1 day, filter the transparent liquid, add 5g of edible nucleic acid, 1.8kg of ascorbic acid, 0.5kg of glucose, 1kg sucrose, finally add 0.2kg sodium alginate (soaked in a small amount of warm water first, then heated and dissolved), stir until it is completely dissolved, take 10L of 75% choline chloride aqueous solution, add the above solution, and finally add 30L glycerin Add the above solution, the pH value is 6.5-7.

Embodiment 2

[0034] Embodiment 2: use the plant antifreeze liquid prepared in embodiment 1, test in the muskmelon field planted at Song Xijun's family, Wangtai Town, Haicheng City, Liaoning Province: On March 16, 2002, the local outdoor temperature was 10-15°C, and the temperature dropped suddenly. The temperature dropped to minus 2°C. At this time, the heating equipment in the greenhouse had been removed, and the temperature in the greenhouse had dropped to a low temperature of about 5°C above zero. The frozen melon seedlings were sprayed, and a piece was left as a control. After four days of return visits, 90% of the frozen melon seedlings had greener leaves, while all the frozen melon seedlings in the control field died, and the loss of 3,000 yuan was recovered.

Embodiment 3

[0035] Embodiment 3: use the plant antifreeze liquid prepared in Example 1, test in the kidney bean field planted by Li Xiuchun, Anfujia Town, Anshan City, Liaoning Province: In March, 2002, the local outdoor temperature was 10-15°C, and the temperature dropped suddenly. At this time, the heating equipment in the greenhouse has been removed, and the temperature in the greenhouse has dropped to about 2℃ above zero. Due to the frost damage, the kidney bean leaves withered and turned yellow, and the crops were sprayed with plant antifreeze. 4 During the return visit on March 5, it was found that 80% of the frozen kidney bean sprouts had improved significantly, the leaves were tender green, and the growth was very good. I visited again on April 26 and saw that some of the kidney bean fruits were ripe, and there was a slight surplus after recovering the loss.

Abstract

The plant antifreezing liquid is compounded with purslane as main material and through extraction, and compounding the extracted liquid with ascorbic acid, glucose, cane sugar, algin sodium, glycerin and choline chloride. The present invention as one kind of natural preparation has no toxicity, no harm and no environmental pollution, and may be sprayed to foliage, flower and bud easily to reach effective antifreezing period of 10-20 days.

Description

technical field [0001] The invention relates to a plant antifreeze liquid and a preparation method thereof. Background technique [0002] In northern my country, the temperature often changes in early spring, late autumn and early winter, and crops are often invaded by cold waves due to sudden changes in the weather. The sharp drop in temperature caused severe freezing damage, which caused the loss of some tissues such as leaves and flowers. Even for some cold-resistant crops, the cold-resistant exercise in the crops had not been completed at the end of autumn, resulting in huge losses. [0003] The impact of freezing damage on crops is mainly caused by the freezing of plant cell spaces and plant cell freezing. When the temperature drops rapidly, the water in the cell spaces first freezes, and the water vapor in the surrounding cells flows into the ice crystals in the cell spaces. Coagulation increases the volume of ice crystals and causes mechanical damage to the cell prot...
